1. The inverters (WELLSEE USB Power Adapter WS-IC500 500W) are
manufactured by imported components with an advanced circuit design
and 98% conversion efficiency. The strict management system of
production and quality with modern assembly lines ensures the
2. The products (USB Power Adapter) have complete specifications,
which are aimed at different international standards, there are a
total number of models available for selecting.
3. The internal protective circuits prevent electrical pulses or
voltage fluctuations effectively, which can withstand the large
impact power of the electrical appliances, such as compressors,
televisions, monitors etc. with a safe start. The power switch can
cut off the internal power supply completely, which protects the
storage battery from damages.
4. The self-protection design makes it possible that it will stop
working automatically when the voltage is lower than 10V, which
guarantees that the storage batteries have enough power to start
5. The USB Power Adapter will stop working automatically when
overheating or overloading, and start again automatically when the
condition returns to normal.
6. It works without noise, which can be used without maintenance
for years by normal operation.
7. It has a diversity of input and output ways: 12V input, 24V
input, cigar lighter input; 220V AC output, 110V AC output etc.,
which can meet the demand of both domestic and international users
for mobile alternating current.
8.The USB Power Adapter WS-IC500 500W adopts an aluminum alloy
casing with a beautiful shape and the technique of a high pressure
plasma oxidation surface with high hardness and oxidation
9. Output waveform: modified sine wave (distortion rate <1.5%)
Characteristics of safety:
1. Overload protection, the power will be automatically cut off.
2. The integral fuse provides the safety guarantee.
3. Low voltage warning, the power will be automatically cut off
4. Overvoltage protection, the power will be automatically cut off.
5. Overhumidity protection, the power will be automatically cut
6. Short circuit protection, the power will be automatically cut
